What is it like to be a flower?
We have our life that we have. We can look at another life and compare but the experience is not complete. Our cycle is here and now until we are unable to be here and now. At this point we expire when we are no longer being.
Why think about what it is like after expiration when you have your life today. Why think of past or future lives when you have now. Today is a great day for you to begin your practice. If you only have five more minutes alive, then now is the time to be aware.
